Nope, ambient temps in my computer room are around 70F/24C. I'm sure part of it is that my rad is a blackice stealth 360, but it's also likely that the software is reading the temps wrong. Still, the lowest it gets is 8C; when I start up a web browser (like right now) or other program it'll bounce between 8C and 26C. Haven't tried a game yet to see what that does; I would expect when more voltage is run thru the CPU the temps will jump.
